The introduction of the SRAM T-Type Transmission has shed a light on why the Universal Derailleur Hanger (UDH) standard exists and why SRAM worked to slip a Trojan Horse of a standard through the gates of the bicycle industry. While this new frame standard has caused some headaches among framebuilders, it does bring with it a few benefits for the handbuilt bicycle that we think outweighs the negatives.

UDH = Good

UDH = Not so Good

Verdict

After all of that description, here’s the short version: we like the Trojan Horse. While there are some downsides to this new standard, the base idea is good and it will only improve with time as we continue to develop and adapt our designs to work with this standard. It works with the latest drivetrains (sorry, TRANSMISSIONS. . .) on the market, solves some pretty critical tolerance stack issues, and the range of compatible drivetrains will only grow over time.
